DIGITAL ZOOM
For horizontal wobble correction, a fixed ratio of electronic zooming needs to be maintained in the
electronic zoom, and for vertical wobble correction, employment of a high density CCD is required. The
threshold for the correction of hand wobble is dependent upon the number of effective lines of the high
density CCD and the horizontal zoom ratio of the electronic zoom.
2. System block configuration II (electronic zoom and special effect blocks)
Fig. 2 Camcorder camera system of electronic zoom 2nd generation application
Fig. 2 above illustrates a camcorder a camera system with an electronic zoom function. The difference
between the above system to the camcorder camera system with electronic zoom and hand wobble
correction function is that, the former does not, for the attainment of image stability, employ high density
CCD intended for the vertical correction of hand wobble. The signal process system explained below and
electronic zoom signal process system are identical to the one illustrated in Fig.1. As for this camcorder
camera system, it is important that all aspects of signal procesing must go through the electronic zoom
process (KS7314) since the repetition of the KS7314 chip enable/disable occuring every time the electronic
zoom turns to on/off would entail screen shift of the image. So to speak, the screen shift occurs just as
much as the electronic zoom processing is delayed develops. In order to compensate for the electronic
zoom system, the video data is delayed to match, the processing delay of electronic zoom, using the
synchronizing signal (burst flag, CBLK or CSYNC), and is then passed to the signal processor (KS7306).
The special effect is implemented in the following manner. The special effects data in serial format,
supplied from the system micom, is first converted to parallel format. The mirror effect in horizontal
direction and the mosaic effect in vertical direction are implemented, controlled by the read address of line
memories for horizontal expansion. The read/write enable signal while the mosaic effect in horizontal
direction is achieved by the conversion of sampling frequency against the fully interpolated image data. In
particular, the mosaic effect can also be achieved in EIS mode.
